Ro Antiscalant is a pretreatment water additive for reverse osmosis system that is highly effective in preventing the membranes from scaling. Before the feed water enters the reverse osmosis membrane, an antiscalant is injected into the water and sent through the system. There are a large number of chemical suppliers who supply a variety of proprietary antiscalants and dispersants to improve the operation of ro and nf systems. Antiscalants are a family of chemicals designed to inhibit the formation and precipitation of crystallized mineral salts that form scale. RO antiscalant helps to control inorganic scales of calcium, magnesium, barium, strontium, fluoride, iron and silica. RO antiscalant ensures above 80% reduction in scaling tendencies if used continuously. Antiscalant for Reverse Osmosis is invulnerable in handling and use with a very high recovery rate of membrane.
